What is the measure of Angle B

119

Step-by-step explanation:

Angle C= 62

So you add 62 + 57 which gives you 119

All angles must add up to 180 so you subtract 119 from 180 which gives you 61

Since angle A is 61 and a straight line angle is 180 you subtract 61 from 180 to give you angle B

180 - 61 = 119

therefore your answer is 119

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.
